yes!!! There is a huge quality difference between these modes but every has 
its own pros and cons. That why the option should be
- in
- in cleartext and not in number form and
- it would be better, if you can apply the q-value somehow in the 
raw-converting process and not as a fixed default value.
You do not see difference when you take a thumpnail sized image, you have to 
view it 1:1. Please see the details on
and look at the crops.
You will see AHD (q=3) has a completely different behavior in decoding fine 
structures than vng.
